BMW created the BMW i3, launched in 2013 with a passenger cell made largely from carbon-fibre-reinforced plastic.
The i3 was developed as the first production model of BMW’s electric-focused i sub-brand. Its passenger cell, called the Life module, used carbon-fibre-reinforced plastic to reduce mass. A separate aluminum Drive module carried the electric drivetrain, battery, suspension, and structural components.
The standard i3 used an electric motor driving the rear wheels. BMW also offered versions with a small gasoline engine known as a range extender, which generated electricity to support the battery when needed. Availability of that option varied by market and model year.
The i3 entered series production in 2013 and was assembled in Leipzig, Germany. Its construction and unusual rear-hinged rear doors distinguished it from conventional compact hatchbacks. The i3 should not be confused with BMW’s later i4 or iX electric models, which use different vehicle platforms and body formats.
